Steps
Install feast and scaffold a repo with feast init my_project, then cd into feature_repo
Configure feature_store.yaml with a provider and an online_store type (sqlite, redis, or dynamodb)
Define Entity and FeatureView objects (with schema, ttl, and a source) in Python, then register them with feast apply
Backfill and keep the online store current by running feast materialize-incremental $CURRENT_TIME on a schedule
Confirm feature freshness by reading back features for a sample entity from the online store
Known gotchas
Feature view names must be globally unique within a project or feast apply will reject them
materialize-incremental derives its backfill start window from each FeatureView's ttl, so a missing or misconfigured ttl silently changes how much history gets loaded on first run
Switching online_store.type in feature_store.yaml requires re-running feast apply to provision the new store's tables before materializing again
